BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofChrysanthemum plant, botanically known as Chrysanthemum x morifolium,typically grown as a cut flower Chrysanthemum and hereinafter referredto by the name ‘DLFSHAD3’.

The new Chrysanthemum plant is a product of a planned breeding programconducted by the Inventor in Maasdijk, The Netherlands. The objective ofthe breeding program is to create new cut flower Chrysanthemum plantswith numerous attractive inflorescences.

The new Chrysanthemum plant originated from a cross-pollination inFebruary, 2015 of a proprietary selection of Chrysanthemum x morifoliumidentified as code number db 34294, not patented, as the female, orseed, parent with a proprietary selection of Chrysanthemum x morifoliumidentified as code number db 10460, not patented, as the male, orpollen, parent. The new Chrysanthemum plant was discovered and selectedas a single flowering plant from within the progeny of the statedcross-pollination in a controlled greenhouse environment in Maasdijk,The Netherlands in March, 2016.

Asexual reproduction of the new Chrysanthemum plant by vegetativeterminal cuttings since March, 2016 has shown that the unique featuresof this new Chrysanthemum plant are stable and reproduced true to typein successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Chrysanthemum have not been observed under allpossible combinations of environmental conditions and culturalpractices. The phenotype may vary somewhat with variations inenvironmental conditions such as temperature, daylength and lightintensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘DLFSHAD3’. These characteristics incombination distinguish ‘DLFSHAD3’ as a new and distinct Chrysanthemumplant:

-   -   1. Upright plant habit; uniform growth habit.    -   2. Dark green-colored leaves.    -   3. Uniform and freely flowering habit.    -   4. Strong upright flowering stems.    -   5. Daisy-type inflorescences with light purple-colored ray        florets and bright yellow green-colored disc florets.    -   6. Resistant to Fusarium and White Rust.    -   7. Relatively tolerant to high and low temperatures.    -   8. Good postproduction longevity.

Plants of the new Chrysanthemum differ primarily from plants of thefemale parent selection in ray floret color as ray florets of plants ofthe new Chrysanthemum are light purple in color whereas ray florets ofplants of the female parent selection are light purplish pink in color.In addition, ray florets of plants of the new Chrysanthemum reflex withdevelopment whereas ray florets of plants of the female parent selectiondo not reflex with development.

Plants of the new Chrysanthemum differ primarily from plants of the maleparent selection in ray floret color as ray florets of plants of the newChrysanthemum are light purple red in color whereas ray florets ofplants of the male parent selection are white in color.

Plants of the new Chrysanthemum can be compared to plants ofChrysanthemum X morifolium ‘Chelo’, not patented. In side-by-sidecomparisons, plants of the new Chrysanthemum differ primarily fromplants of ‘Chelo’ in ray floret color as plants of the new Chrysanthemumhave light purple-colored ray florets whereas plants of plants of‘Chelo’ have darker purple-colored ray florets. In addition, ray floretsof plants of the new Chrysanthemum are more convex than ray florets ofplants of ‘Chelo’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of thenew Chrysanthemum plant showing the colors as true as it is reasonablypossible to obtain in colored reproductions of this type. The photographon the first sheet (FIG. 1) comprises a side perspective view of atypical flowering stein of ‘DLFSHAD3’ grown as a spray-type cut flower.The photograph on the second sheet (FIG. 2) is a close-up view of upper(top of the photographic sheet) and lower (bottom of the photographicsheet) surfaces of typical leaves (left) and inflorescences (right).

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations andmeasurements describe plants grown during the late spring in ground bedsin a glass-covered greenhouse in Maasdijk, The Netherlands and undercultural practices typical of commercial cut Chrysanthemum production.Plants were initially given long day/short night treatments followed byshort day/long night treatments to induce flower initiation anddevelopment. During the production of the plants, day temperaturesranged from 18° C. to 25° C., night temperatures ranged from 20° C. to22° C. and light levels averaged 8 klux. Plants were grown assingle-stem spray-type plants and were eleven weeks old when thephotographs and the description were taken. In the followingdescription, color references are made to The Royal HorticulturalSociety Colour Chart, 2015 Edition, except where general terms ofordinary dictionary significance are used.
